HAY-CARRIER.

SPECIFICATION forming part of Letters Patent No. 290,591, dated December 18, 1883.

I Application filed September 15,1883. (No model.)

will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in hay-carriers, and it consists, first, in the combination of the lever,which serves to lock the carriage in position with the trip-pulley, the pulley being made to come in contact with the lower edge of the lever when the pulley is drawn up into place by the draftrope; second, the combination of the lever, which is used as a brake, or for additional purposes, with a swivel permanently attached thereto, and to which swivel one end of the draft-rope is attached; third, the combination of the track, whether formed from a wooden bar, or metallic rod or cab1e,with an eccentric collar, which is attached thereto, and which is adapted to be turned around, and thus to be adjusted to theend of the locking and brake levv er,so that a proper adjustment ofthe brake may thereby be secured, and the hook may catch over the edge of the collar and hold the carriage in place; fourth, in a brakc-levcr,which is made Vshaped at that end where it comes in contact with the draft-rope, so as to be broader at the heel than at the point, and thus adapted to fit any-sized rope.

Figure l is a side elevation of a carrier em bodying my invention. Figs. 2, 3, and 4 are detail views of the same.

X represents the tracl:,which may be formed either of wood or iron, of any desired shape in cross-section. that may be preferred. The carriage F is supported upon this track by means of the pulleys AL In the extreme lower end of this carriage is pivoted the carrier-pulley B, over which the draft-rope R passes.

In the lower corner of the frame is pivoted the combined brake and locking lever D, which has the shoulder H, formed upon its outer end, and which has its other end grooved, as shown in Fig. 4:, for the purpose ,ent sizes.

of forming a brake upon the rope ll. Permanently secured to this lever D, at any suitable point between where it is pivoted and its brake end, is a swivel hook or cye,Gr, to which one end of the (lraftrope R is attached, and which swivel is adapted to turn-in order to let the twist out of the rope. This swivel is of great importance in a carrier, for it revolves freely around in the lever, and allows the twist and kinks in the rope R to either straighten out themselves, or to be easily straightened out by the operator.

The trip-pulley 0, provided with the usual hook to which the hay-fork is attached, is

placed upon the rope R in the usual manner, and when this pulley G is raised into position its center strikes against the lower edge of the lever D, as shown in Fig. 3. The lower edge of this lever will preferably be made rounding, so that when the pulley is raised upward against it the center of its groove will come in contact with the lever without the danger of injuring the pulley in any manner, and thus dispensing with guards and other devices to protect it. The draft-rope B, being attached to the lever D in the manner shown, causes a downward pressure upon the inner end of the lever in proportion to the weight which is hung upon or attached to the trip-pulley. In order to cause this lever D to act more effectually as a brake, its end has a V-shaped groove or recess made in it, and the end is made broader at its heel than the upper point, as shown in Fig. 4. By this construction the lever is made to adapt itself to ropes of differ- If the rope is a large one,the lever will bear upon it only at its heel or widest point, and if but a half-inch rope is used, the

lever willbear upon it at or near its upper point. In order to enable this end to act to a still greater advantage, this grooved end is made serrated, as shown, which serrations are graduated to fit different-sized ropes. These serrations help the brake to adapt itself better to the rope, and thus make a better brake.

By attaching the end of the draft-rope R to the lever D at a point between where it is pivoted and the end which forms the brake on the rope, the weight of the material being elevated is utilized to help look the rope as it is being carried back to where the load is to be deposited. Being assisted in this way,the

ICO

brake does not require to take such a solid I to be attached to the brake-lever between 60 bite on the rope, and is therefore easily released. The biting-edges of the brake do not need to be so sharp, and are therefore easier on the rope. The heavier the load to be carried the more solid the catch on the rope, and when the load is discharged, the hold on the rope is principally released, so that it does not take much power to raise the brake from the rope and allow the hook II to engage with the catch. By this means all additional weights, levers, springs, or other devices which are usually employed to operate the brake can be dispensed with, and a much sinipler and more effectual andinexpensive braking device will be produced.

' Secured to the track is a collar, K, which has the hole through it made to one side of its center, so as to form an eccentric. By turning this collar around, the edge which forms the catch E can be raised or lowered, and by this means the lever D can be adjusted to suit different-sized ropes, and to compensate for wear. By the close adjustment of the brake with the rope,no unnecessary movement is required to allow the hook H to engage with the catch.

The tripping or check rope O is attached to the trip-pulley frame, which is provided with eitheraround-edgehole orasmall guiding-pulley for this purpose. The rope is attached to this pulley-frame for the purpose of preventing it from getting twisted around the fork, and also to enable the operator to draw the fork back with the carrier, should it become either purposely or accidentally disconnected from the pulley-hook.

This carrier can be made of any suitable material, and can be put together in any suitable manner, and all the improvements above described can be used to work on a wooden,

steel, or iron rod or cable track, with the exception that that portion of the track to which the catch or collar is attached must be made round, so that the collar can be turned, or the collar must be made large enough to encircle the brake. I have shown the lever D used as a combined brake and locking lever; but, if preferred, it can be divided into two parts, and a separate and independent lever be used for each purpose.

These levers may be placed side by side upon the same pivot, or upon separate pivots. In

this event the draftrope will be attached to the brake-lever, and the trip-pulley will come in contact with theloeking'lever; or the brake lever alone can be used, andother means can be employed for locking the carriage in position upon the track. The draft-rope is shown where it is pivoted and the end which forms the brake; but it may be attached in any other suitable manner, the essential point being to so attach it that the weight of the material being elevated can be used to force the brake 6 5 against the rope; but it may be, if desired, attached to the lever, without reference to helping the brake. or for the opposite purpose of releasing the brake.

I do not limit myself to any precise construction and arrangement of parts, for these may be varied without departing from the spirit of my invention.

Having thus described my invention, I claim-- v 1. In a hay carrier or elevator, the combination of the brake-lever D, which is pivoted to the carriage, and which has the end of the draft-rope attached thereto, so that the weight of the material being elevated will cause the brake end of the lever to bear against the rope with the swivel G, which is permanently attached to the lever, the brake end of the lever being made V-shaped, so as to be adapted to fit over the top of the rope, substantially as shown. s

2. In a hay carrier or elevator, the lever D, having its end provided with aV-shaped groove or depression, and having this depression provided with graduated serrations, so as to adapt the end to fit upon different-sized ropes, substantially as set forth.

3. In a hay carrier or elevator, the lever D, having its end provided with a V- shaped groove or depression, and having the heel of 95 the end made wider than at the point, substantially as specified.

.4. The combination of a hay carrier or elevator, and a locking device connected thereto, with the eccentric collar or catch, which is attached to the track, and which is adapted to turn around, substantially .as shown.

5. The combination of the lever D with the trip-pulley O, the lower edge of the lever being so shaped as to bear against the center of 105 the top of the pulley when the pulley is raised upward by the draft-rope, substantially as set forth.

6. The combination of the lever D with the swivel permanently attached thereto, as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
